AN AUTOMATIC CUT-OFF SIAMESE CONNECTION.
Within the past few years the value of the Siamese connection, by which the water pumped by two or more fire engines may be massed in one great solid stream, has been thoroughly, often and effectually demonstrated. It has been repeatedly shown that there are cases where a fire obtains such headway and proportions that to control it and prevent its further spread the greatest possible quantity of water must be thrown upon it in the largest available streams and in the shortest possible time. This is what the Siamese connection makes possible.
We need no further excuse for printing an illustration of an automatic shut-off Siamese connection, manufactured by the D. A. Woodhouse Manufacturing Company of New York city. It is, as will be seen, a simple enough device in appearance, similar to the ordinary Siamese connections so long used by our leading fire departments. There was, however, one great disadvantage under which the old-fashioned Siamese labored, which, in the one shown in the cut, has been overcome. In the older appliances, should one of the engines attached to it break down tv fail from any cause, the back flow of water was pretty sure to damage it, or in case a section of hose connecting a machine with the Siamese burst, the back flow was so great as to allow the water to escape through the burst hose instead of the nozzle.
With the device shown there is no danger of any such mishap. The automatic valves at the inlets (which lift up entirely out of the water-way when the engines are at work) arc absolutely positive in their motion, and cannot by any ordinary means be injured in any way. At the moment the stream from either engine gives out the back pressure at once closes the valve. Burst hose can then be replaced, or any machine be thrown out or into service without in any way interfering with the positive working of the Siamese.
These Siamese connections are in use and have given great satisfaction in the fire departments of New York, Brooklyn, Springfield, Mass., Providence, R. I., Denver, Col., Baltimore, Md., and other cities.
The complete Siamese outfit manufactured by the Woodhouse Company comprises, besides this connection, a 25-foot line of 3>4-inch extra Para hose, with a double-swivel pipe stick copper pipe, tapering from 34 inches to 2,’i inches at the tip, and having three special nozzles of 1 1/2, ijz and 2 inches discharge respectively. The steel pipe stick holder is arranged so that the strain is brought on the point resting on the ground, so that two men may readily hold the pipe and control the stream.
